Check Digit Verification of cas no
The CAS Registry Mumber 16271-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,7 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16271-33:
(7*1)+(6*6)+(5*2)+(4*7)+(3*1)+(2*3)+(1*3)=93
93 % 10 = 3
So 16271-33-3 is a valid CAS Registry Number.
